Slight Address Change

I got a form letter today from Aaron. The address in this one is in a slightly different form. Here is his 'new' address...I don't know if it makes a difference.

SPC Marshall, Aaron E.
D CO 3-47 INF
3rd Platoon, RN# 314
5480 Roush Drive
FT Benning, GA 31905-4769

Please still write RN # 314 on the back of your envelope.

All of the information is the same but they used different abbreviations. Like I said, I don't know if it really matters, or if not having these abbv. will delay the mail, I wouldn't think so.
